Acquisition
Green Mining acquires the asset and takes over the operation.
Mineral technology developed over more than a decade.
Green Mining develops and applies a mineral processing route for tailings and low-grade deposits. The work began in 2011 and combines laboratory work, field validation and intermediate-scale operation.
Who we are
What Green Mining does.
Green Mining is a mineral technology company. It has developed a processing route that combines liberation of occluded metals, compact column flotation, selective chemistry and process control, configured for each material. On the gold route, the process does not use cyanide.
The technology applies on two fronts: tailings, material already extracted and deposited, and low-grade deposits, where lower capital and operating costs can make previously uneconomic areas viable.
Every project starts with material characterization. Technical and economic results are presented with assumptions, scope and limitations, for that material and under those conditions.
Trajectory
Development milestones.
2011
Start — development of the flotation route and of the work on liberating occluded metals.
2012
Field validation — at a gold operation in South America, with academic participation from the University of British Columbia.
2017
Intermediate scale — operation in Brazil for about 18 months, processing tailings continuously.
2025
Reference laboratory — a unit in Brazil dedicated to material characterization and to developing chemistry by material type.
Today
Projects — assessment of tailings and low-grade assets and development of projects with modular plants.
Laboratory, field and operation, over more than a decade.
How we work
Partnership formats defined per project.
The format is defined case by case, after the technical and economic assessment. Hybrid structures are possible.
Joint venture
Capital, risk and results shared with the asset owner, in a structure defined through joint due diligence.
Royalty
Green Mining operates; the owner keeps title and receives a royalty.
Contract operation
Green Mining operates under a service contract; the owner keeps title and production.
External references
Validations and intellectual property, with declared scope.
University of British Columbia
Academic partnership since 2012, with participation in the field validation carried out at a gold operation in South America. The scope of the work is described in the technical documentation.
Laboratory audit
Independent laboratory audit, reference certificate GO2511449. Scope, date and audited samples are recorded in the technical documentation.
Granted patent
Patent granted on the system. Number, jurisdiction and coverage are provided in the technical documentation.
About the data on this sitePerformance figures depend on the material and on the conditions of each project. For that reason they are not presented as a public promise: they are part of technical material, with methodology and scope, available to qualified parties.
